Crèvecœur, in his introductory letter (letter I) in Letters from an American Farmer, comes across as a very condescending way. He seems to be saying that his actions (being welcoming, hospitable, and kind) are contradictory to his true nature. He seems to be stating that he is not as welcoming as he presents himself based upon the fact that he can write with "propriety and perspicuity."
He blatantly states that he, and his welcoming nature, has been misjudged. Instead of learning from his visitor, he found the conversations humorous and entertained him immensely.
Therefore, Crèvecœur represents himself in very contradictory light. At times he seems very gracious of what he learned about the world. At other times, he seems to have only acted out of custom.
